Filing history and where it was sold

Motobravo filed one certificate under this family, for model year 2011, sold as 50-state, California included.

The vehicle itself is recorded as built by the same company, ZHEJIANG LEIKE MACHINE INDUSTRY CO., LTD in China — engine and chassis from one source.

Certified emission levels: CO 6.7, HC 0.6 g/km.

Other records carrying the same engine code

Motobravo certified an engine with this code under 3 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

• 9MTBC0.15N1M (2009)
• AMTBC0.15N1M (2010)
• CMTBC0.15N1M (2012)

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
